Core section of overland 220 kV cable line with longest-distance transmission in China starts shield tunneling

Recently, the STATE GRID has started shield tunneling for the core section of the overland 220 kV cable line, boasting the longest-distance transmission in China. This pivotal part, known as the Green Expo Garden section of the Qiuteng-Wangjiang 220 kV project, will significantly enhance the power mutual aid capabilities on both sides of the Yangtze […]

Children with autism excel at motion detection test

On a test of visual perception, children with autism perceive moving dots with more clarity than children without the disorder. The results, published in the May 6 Journal of Neuroscience, reveal a way in which children with autism see the world differently. When asked to determine the overall direction of a mess of dots moving […]

Stimulating nerve cells stretches time between thinking, doing

A zap to the head can stretch the time between intention and action, a new study finds. The results help illuminate how intentions arise in the brain. The study, published in the May 6 Journal of Neuroscience, “provides fascinating new clues” about the process of internal decision making, says neuroscientist Gabriel Kreiman of Harvard University.

Wandering planets, the smell of rain and more reader feedback

Free-range planetsAstronomers are puzzling over some space oddities: planets that don’t orbit stars. In “Wandering worlds” (SN: 4/4/15, p. 22), Ashley Yeager explored how these lonely rogues may alter the definition of a planet. Tim Geho wanted to know more about how scientists locate homeless worlds. “Where does the light come from that allows rogue […]

Possible nearest living relatives to complex life found in seafloor mud

Cold mud from the seafloor has revealed signs of a new group of microbes that could be the nearest living relatives yet found to the domain of life that includes people and other creatures with fancy cell structures. That mud carries DNA of a previously unknown and unusual phylum of one-celled microbes, researchers report online […]

Underground heat pollution could be tapped to mitigate climate change

The secret to efficiently heating some buildings might lurk beneath our feet, in the heat that humans have inadvertently stored underground. Just as cities warm the surrounding air, giving rise to urban heat islands, so too does human infrastructure warm the underlying earth (SN: 3/27/09). Now, an analysis of groundwater well sites across Europe and […]

Here are experts’ answers to questions about COVID-19 vaccines for little kids

Four weeks ago, the U.S. Centers for Disease Control and Prevention signed off on COVID-19 vaccines for young children. Days later, doctors’ offices and clinics began rolling out shots for babies and toddlers. In Portland, Ore., a clinic featuring bubbles, toys and a dance party delivered more than 1,100 shots in two days. In Arizona, […]
